SM Entertainment unveiled 2 photos via Girls' Generation's Twitter on April 6. The photos have snippets of Taeyeon's face with mysterious letters and numbers.
Of course, netizens were quick to break down the mystery of the secret codes. It's claimed that CON= concert, B017= 2017, 05=May, L= 12, and AD=14 (the letters and their spots in the alphabet = the number), ultimately, meaning that Taeyeon is scheduled for a solo concert on May 12-14. Meanwhile, 'PREOANS' is assumed to be signifying the title of the event.
No official announcement has been made regarding Taeyeon's solo concert.
Stay tuned for updates!
